Brendon Smith & Mayur Ladwa
Brendon and Mayur are software developers in BlackRock. Brendon manages the investment risk team and is also responsible for delivering various fixed-income tools in BlackRock. Mayur works in the core client processing team dealing with tools around the client investment lifecycle. Both of them are passionate about big data technologies and spend a lot of their own time learning new ways of solving data-related challenges.
Creating data warehouse solutions using Apache Spark
Historically, majority of companies have been looking at various data warehouse solutions, possibly with structured data in a star schema environment. Given the increasing amount of data and performance benefits of newer technologies, in this talk, Brendon and Mayur will go through how we use technologies such as Spark and a HDFS compliant file system with columnar storage for a multi-data centre architecture that allows employees firm wide to run analytical queries.

The C* Spark connector under the covers
We've seen a lot of hype about integrating C* and Spark, this will be a 10 minute deep dive into how Spark partitions are built from C* data and how the connector writes data into C* (and how you can throttle it). It is assumed you already understand Spark and C*.
What's new in Cassandra: 2.2 and a look at potential 3.0 features
Cassandra 2.2-rc2 has just been released which means that 2.2 is just around the corner. Let's have a look at the new features and how they'll affect the way you model data in C*. We'll go through:
- JSON support
- User defined functions
- User defined aggregates
- Role based authentication
Then we'll step into the future and take a look at 3.0 with Materialised Views being the biggy. However be warned: all 3.0 examples are off trunk and the exact syntax/feature may change come release time!
In addition to the talks there will be, as usual, plenty of opportunity to meet other Cassandra users and enjoy robust discussions around NoSQL.
